MDS concerns

I am new nurse, LPN with less than two years experience was offered MDS position got decent raise and supposedly better schedule. However I am in a facility that has average of 140-150 residents. We have myself and a FT RN as MDS. I can do all the assessments and can do care plans, however can not sign off on care plans. SO have to print so the RN can sign off on the care plans and need to be "supervised" while creating them. I also can't sign off on one section of the assessments. I love the position, did accounting before nursing so am detail oriented and think it is huge opportunity for LPN especially new nurse. Am currently back in school, as they have pushed me to work on my RN. However the facility I work for, has me on call very often and always pulls me to the hall even when I am not on call. It is frustrating, we also have management and personnel issues. No one really does their jobs, we have no wound nurse and all of this stuff effects my ability to do my job accurately. I do get compensated well I think considering where I live and my limited experience but feel I do a very good job and have been ready to leave this position and have asked them to put me back as a hall nurse because I have addressed the issues numerous times with my DON and Admin and not much help. We are constantly pushed to do things too quickly and things change constantly so it is frustrating. I could love this position in a company that valued their employees and that was consistent. I just feel I am getting burned out and they won't fix the issues in management. Any ideas or thoughts? I mean I really am blessed but am frustrated with the way things are run and how it all comes back down to me doing my job effectively.
